Circular-saw blades come in a variety of sizes and styles; they can be made from different materials and can feature various kinds of teeth. Choosing the right blade for a job can be tricky.
The steel blade has bent teeth that are good for cutting through wood of most any depth. This type of blade dulls easily but is inexpensive to replace.
The carbide-tipped blade has teeth that are brazed to the body of the blade, and then sharpened. A carbide-tipped blade is good for cutting wood of about any depth and has a longer life than a steel blade.
The crosscutting blade has a large number of carbide teeth per inch, which enable it to make smooth cuts.
The ripping blade has a flat-top grind, meaning that its tips are flat. The ripping blade has fewer teeth per inch, so its cuts are rougher. Ripping blades are carbide-tipped or steel.
The combination blade can make crosscuts or rip cuts. It has flat-topped teeth for cleaning the kerf, and because the teeth point in alternate directions, the blade can make smooth cuts. It also has deep gullets for ripping and smaller gullets for crosscutting.
The plywood blade has a large number of small teeth, making it useful for splinter-free sawing on plywood and paneling.
The aluminum-cutting blade has thick teeth for cutting through aluminum and other light metals.
